Was Jonah swallowed by a fish or whale?

The Bible story of Jonah doesn't actually specify what kind of sea creature swallowed him. It simply says a "great fish".

However, over time, the interpretation of this "great fish" as a whale became popular, likely due to the whale's massive size and association with the sea.

It's important to note that:

* The Bible doesn't explicitly state it was a whale. The term "great fish" leaves room for interpretation.

* There are other possibilities. Other large sea creatures existed and still exist that could have swallowed Jonah, such as a giant squid or a shark.

Ultimately, the exact nature of the "great fish" is a matter of interpretation and debate. The story serves as a powerful allegory about God's mercy and forgiveness, regardless of the specific creature involved.
